If qtsvg is updated, but no other changes are made, will qtimageformats (and all the other packages that inherit from qtsvg) need to be rebuilt as well? Looking at `guix refresh -l` and `guix gc --references` suggests the answer is "no". I know this is a contrived example; if qtsvg is updated, it's likely that all the Qt packages will be updated as well. > + (name "qtimageformats") > + (version "5.6.1") > + (source (origin > + (method url-fetch) > + (uri (string-append > "https://download.qt.io/official_releases/qt/"; > + (version-major+minor version) "/" version > + "/submodules/" name "-opensource-src-" > + version ".tar.xz")) > + (sha256 > + (base32 > + "020v1148433zx4g87z2r8fgff32n0laajxqqsja1l3yzz7jbrwvl")))))) > + > (define-public qjson > (package > (name "qjson") > -- > 2.8.3 > >
